6    
7    o pkg/seaice: overhaul of thermodynamics
8     - growth.F and groatb.F are replaced by new routine seaice_growth.F
9     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
10     - move a few global fields out of SEAICE.h into seaice_growth.F and
11       make them 2D (FICE/QNETO/ ...)
12     - remove FO (it is the same as QNETO)
13     - introduce a few local fields to avoid modifying external fields such
14       as atemp, etc.
15    
16    checkpoint58s_post
17    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
18      changed exf_set_gen.F so that
19        genperiod=0 means input file is one time-constant field and
20        genperiod=-12 means input file contains 12 monthly means
21    o CG2D: use pre-computed solver main-diagonal (stored in common block);
22      this affects truncation error ; generate new output file for exp. which
23      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
24        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
25        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
26        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
27        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
28        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
29    o start implementation of deep-atmosphere and anelastic formulation
30    o verification: remove 2nd copy of input files and use script "prepare_run"
31      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
32    o mom_common/vecinv/fluxform: fix a few initialisation isssues
33    o profiles: fix for multithreaded case
34    
35    o diagnostics: rename few diags:
36      s/'PRESSURE'/'RCENTER '/g
37      s/'TICE    '/'oceFreez'/g
38      s/'TAUX    '/'oceTAUX '/g
39      s/'TAUY    '/'oceTAUY '/g
40      s/'SWFLUX  '/'oceQsw  '/g
41      s/DIFx/DFxE/g
42      s/DIFy/DFyE/g
43      and add few ocean-forcing diagnostics:
44      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
45    o modifications to pkg/seaice/growth.F and budget.F, which change results of
46      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
47      as actual snow thickness.  It now refers everywhere to effective snow
48      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
49    
50    checkpoint58r_post
51    o modifications to pkg/seaice/growth.F, which change results of
52      lab_sea experiment: fixes pertain to melting snow over open water, to
53      masking EVAP under sea ice, and to using the correct AREA variable for
54      computations of EVAP, PRECIP, HSNOW, and GHEFF
55    o add ability to read bathy, salt, and theta using MNC (off by def)
56    o add flooding algorithm and advection of HSNOW for pkg/seaice;
57      both are turned off by default and do no change any results
58    o seaice advection with pkg/thsice: a step toward the use of non-linear
59      advection scheme, but #ifdef or commented out for now (requires more EXCH).
60    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
61      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
62      in natl_box (affects results @ truncation level: update output.txt)
63    o multi-threading and IO:
64      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
65      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
66        (needed to work with SingleCpuIO): tested in all verif. exp.
67    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
68      affects the results (but none of the verification test uses this scheme).
69    o Adding some pkg/diagnostics capability to pkg/seaice
70      (will certainly be subject to changes)
71    o ctrl: adding new control variables:
72      lwflux, lwdown, evap, snowprecip, apressure, runoff
73    
74    checkpoint58q_post
75    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
76      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
77      high_res_cube configuration by 4% on Columbia.
78  o clean-up multi-threaded problems (reported by debugger tcheck on ACES);  o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
79    add (in global_with_exf/code) a version of EXF_INTERP_READ without    add (in global_with_exf/code) a version of EXF_INTERP_READ without
80    dynamical allocation (seems to work in multi-threaded).    dynamical allocation (seems to work in multi-threaded).
